Conditions for veining and origin of mineralizing fluids in the Alpi Apuane (NWÂ Tuscany, Italy): Evidence from structural and geochemical analyses on calcite veins hosted in Carrara marbles

► We combine structural and geochemical data on calcite veins from the Alpi Apuane (Italy). ► We estimate the thermo-baric conditions at the time of veins formation. ► We define the composition and origin of vein-forming fluids. ► We reconstruct the time-depth path for Carrara marbles.
